Hi. We are in the area for a few weeks and during that time we are flying up to Thessalonika for a few days. Is parking available at the airport, if so what is the procedure, if not any suggestions, please.

Haven't used it this year but last October very easy drive in go through the barrier on the left (after the hire car parking),take a ticket from machine park car, stroll across to the terminal. On returning give ticket to the man in the hut and he will feed the pay machine for you it cost then 3€ per day.

Kalamata Park & Fly have been recommended to us. Their premises are on the right (coming from Kalamata) immediately before the roundabout accessing the airport. On their card their contact email is iliok77@gmail.com
Has anyone any experience of this service?

I have just made a booking with Kalamata Park & Fly. It is on the right as you approach the Airport Roundabout from Kalamata direction, just before the Europacars compound.
Konstantinos was exceptionally helpful and responded immediately to my emails. His telephone no. is 6987080426.
His daily rate is 2 Euros and he will negotiate the rate for longer terms.
